Abstract
AbstractFor a number of years the Swedish State Railways (SJ) has been involved in life cycle cost (LCC) acquisitions.1 The best known example is the recent acquisition of rapid trains. Logistics support analysis (LSA) is a natural supporting activity and a number of analyses have also been performed on existing material. This kind of analysis was previously done only to a minor extent. Therefore it is not surprising that the potential for cost‐effective improvements has been very large — in fact larger than expected.This paper will report from three different investigations, each of which illustrates various types of improvements in the existing logistics support system. These three investigations are Spares holding of pantographsA pantograph is the item that connects the electric driven locomotive with the power line. Analysis of the automatic train control (ATC) system Logistics support analysis of traction engines. The major conclusions from the studies are twofold: This type of analysis is very profitable, and the present availability of computer support in fact makes it even more so. There are a number of practical and organizational problems linked to the introduction of such analyses. SJ is not unique in having these kinds of problems.
